基于ARM和DSP的齿轮噪声测试系统

摘要

In order to solve the problems that the traditional gear noise measurement is influenced by human factors ,the gear mesh noise measurement and analysis system based on ARM and DSP was designed. The DSP was used to complete the noise signal acquisition and data preprocessing. A set of signal analysis and graphical display software was developed based on WinCE 6.0. Combined with touch screen system,the test parameters input and communication settings were completed. By experimental verification in Beijing Gear Works site,it shows that the system can analyze the gear glitches and other noise signal frequency, and could be used for the analysis of processing gear.%为了解决齿轮噪声传统测量方法受人为因素影响较大的弊端,开发了一套基于ARM和DSP芯片的便携式齿轮噪声测试系统,利用DSP强大的运算能力完成了噪声信号的采集与数据的预处理；基于ARM下的嵌入式系统操作平台WinCE6.0开发了一套齿轮噪声信号分析及图形显示软件,结合触摸屏系统完成了测试参数的输入和通信设置,并在北京齿轮总厂进行了相关的实验.研究结果表明,该系统可以分析齿轮毛刺等齿轮噪声信号,可用于齿轮加工工艺的分析.
